Fumed-silica surfaces were modified with resorcinol and hexamethylenetetramine complex, and NR/M-silica nanocomposites were prepared in mixing and curing process. Structure and properties of NR/M-silica nanocomposites were investigated by mechanical testing ,cross-linking density determination, transmission electron microscopy, differential scanning calorimetry, fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The results showed that M-silica have obvious reinforcement effect on NR vulcanizate.

Is better than that of using Na〓S merely and the profit per year is over 6, 000, 000 yuan. External potential-control flotation column and The Cu-Mo bulk concentrates flotation separation. With appropriate combination of the principle of sulphide flotation pulp electrochemistry and the technology of flotation column show the advantage over flotation equipment, External potential-control flotation column was studied successfully, laboratory potential-control flotation column was designed and its structural principle, the relationship of electrode structure and the activity of separation, the electrochemistry principle of potential-control flotation column also was investigated.

用具有较强电化学还原能力的无机物（如硫化钠、连二亚硫酸盐等）与能和硫化铜矿物表面发生选择性吸附的小分子有机化合物组合使用、成功地实现了混合精矿体系中黄铜矿的抑制、解决了德兴铜矿铜钼混合精矿浮选分离时、硫化钠用量大、生产成本高，生产指标不稳定的技术难题，研究结果表明，用组合抑制剂3.8kg/t可取代生产中硫化钠45kg/t的高用量，并获得优于单用硫化钠的好指标，年直接经济效益600万元以上。

Function : The product uses for natural gum and various kinds of rubber alloy , it is responsivity inextractable antiager SF-98. maleimide system can acceptfreeradical to open double linkage during vulcanization.It forms into horizontal linkage to come into being crosslinking with rubber .it has inextractable antiager effect .and horizontal linkage for thermal oxidation has excellent stability.

功用：该品用于天然胶及各种成合胶，是一种反应性不抽出防老剂，由于马来酰亚胺体系在硫化过程中可接受自由基打开双键，形成横键与橡胶产生交联，起到了防老不抽出的作用，同时这横键对于热氧化作用具有很高的稳定性。

Fourty of them were injected with 1.0 mCi of technetium^99 sulfur colloid at preoperation and 2ml methylene blue dye was injected inoperation in subareolar;radioactive SLNs were identified using a hand-held gamma detector probe,all blue stained SLNs were removed during operation.

其中40例病人术前于乳晕下注射1.0mci的锝^99硫化胶体，术中于乳晕下注射亚甲蓝2ml，同时术中用手握式γ-同位素探测仪确认有放射活性的SLN；行手术解剖法解剖分离出蓝染的SLN。

Fumed silica was surfacely modified with resorcinol and hexamethylenetetramine complex, and the product was then reacted with natural rubber to prepare NR/modified fumed silica (NR/M-silica) nano-composites via a mixing and curing process.

用间苯二酚与六亚甲基四胺络合物对气相法白炭黑进行表面改性，产物与天然橡胶混合，通过混炼和硫化制备了天然橡胶／改性气相法白炭黑(NR/M-silica)纳米复合材料。

Cu-Ni sulfided mine complex locate in BaimaZai of JinPing County is sub alkali iron-super iron, it"s zoning is clear and it"s Ni-Cu-Co melting first and enrichment, its rare earth is rich in right lean light rare earth, but Eu in olive rock is serious to be bad, Gd-Tb is tittles negative abnormity. Above-mentioned show that the mineral is cone from mantle, and didn t mix with crustal substance, and continent tholeiite magma turning into continent tholeiite emplacement after by surging.
